Team of multidisciplinary researchers from Case Western Reserve University (USA) [Victoria Webster; Roger Quinn; Hillel Chiel; Ozan Akkus; Umut Gurkan; Emma L. Hawley; Jill M. Patel; Katherine J. Chapin], have created a 'biohybrid' robot by combining sea slug materials with 3D printed parts, that can crawl like sea turtle. Scientists suggest that in future, swarms of biohybrid robots could be released for such tasks as locating the source of a toxic leak in a pond that would send animals fleeing. They could also be used to search the ocean floor for a black box flight data recorder, a potentially long process that may leave current robots stilled with dead batteries. According to Ms. Webster, PhD student and lead researcher, 'We're building a living machine - a biohybrid robot that's not completely organic - yet. For the searching tasks, we want the robots to be compliant, to interact with the environment. One of the problems with traditional robotics, especially on the small scale, is that actuators - the units that provide movement - tend to be rigid.' Researchers also explain that if completely organic robots prove workable a swarm released at sea or in a pond or a remote piece of land, won't be much of a worry if they can't be recovered. They're likely to be inexpensive and won't pollute the location with metals and battery chemicals but be eaten or degrade into compost. Read on...
